I then read this tidbit in one of my books, regarding the army of the Mithridates of Pontus, an implacable enemy of Rome in the time of Marius, Sulla, Lucullus etc (80-70BC ish)
Hell, if Pontus can do it, a hypothetical Seleucid Empire certainly can.Mithridates, learning perhaps equally from his own past experience and from Sertorious' military mission, had remodelled his army and navy. It is true his large Oriental host still included such lumber as scythe-wheel chariots, which were usually ineffective because they needed an excessively long run in order to gather impetus. He had, nevertheless, equipped his infantry with short sowrds and long shields on the Roman pattern, and had adopted Roman tactical formations.
